[2005] Help Using Tool Strip Control

I'm a little confused and could use some help. I'm doing a project for class and there is a part somewhat confusing. I have a table (tblCourses) with Id#, title, credit hours, and grades. The interface has several tool strip bars with queries to run if you press a particular tool strip. The code asks me to write some sort of statement but the book tells me if I just add a tool strip control associated with the query it should display when the app runs and I press the tool strip. It is pretty confusing and maybe someone knows what type of statement would be appropriate in this case. Here is the code I have:

VB Code:

Public Class MainForm
 
    Private Sub bindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles bindingNavigatorSaveItem.Click
        If Me.Validate Then
 
            'I wrote this part
            Me.TblCoursesBindingSource.EndEdit()
            Me.TblCoursesTableAdapter.Update(Me.CoursesDataSet.tblCourses)
 
        Else
            System.Windows.Forms.MessageBox.Show(Me, "Validation errors occurred.", "Save", System.Windows.Forms.MessageBoxButtons.OK, System.Windows.Forms.MessageBoxIcon.Warning)
        End If
 
    End Sub
 
    Private Sub MainForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load, MyBase.Load, MyBase.Load, MyBase.Load, MyBase.Load, MyBase.Load, MyBase.Load
        'TODO: This line of code loads data into the 'CoursesDataSet.tblCourses' table. You can move, or remove it, as needed.
        'I wrote this part
 
        Me.TblCoursesTableAdapter.Fill(Me.CoursesDataSet.tblCourses)
 
    End Sub
 
    Private Sub exitButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles exitButton.Click
        Me.Close()
    End Sub
 
    Private Sub FillToolStripButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles FillToolStripButton.Click
        Try
            'I'm confused about this part
 
 
        Catch ex As System.Exception
            System.Windows.Forms.MessageBox.Show(ex.Message)
        End Try
 
    End Sub
End Class

As always, all help in understanding is very much appreciated.
